About Q82.5

Q82.5 is the ICD-10-CM diagnosis code for congenital non-neoplastic nevus. It belongs to category Q82 (other congenital malformations of skin), block Q80-Q89 (other congenital malformations) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Q82 (other congenital malformations of skin), Q82.5 is specifically for congenital non-neoplastic nevus. Related codes cover hereditary lymphedema (Q82.0), Xeroderma pigmentosum (Q82.1), congenital cutaneous mastocytosis (Q82.2), Incontinentia pigmenti (Q82.3), ectodermal dysplasia (anhidrotic) (Q82.4), congenital sacral dimple (Q82.6), other specified congenital malformations of skin (Q82.8) and congenital malformation of skin, unspecified (Q82.9).

The conditions in its Excludes2 note aren't part of Q82.5, but may be coded alongside it if the patient has both: Café au lait spots (L81.3), lentigo (L81.4), nevus NOS (D22.-), araneus nevus (I78.1) and 4 more.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 606 (Minor Skin Disorders with MCC, relative weight 1.5728), DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772) and DRG 795 (Normal Newborn, relative weight 0.2022), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 757.32 (vascular hamartomas).
